Abstract (en)
Embodiments of this application disclose a network handover method, a terminal device, and an access point device, and relate to the field of wireless network technologies, to improve a problem in the conventional technology that user experience is affected because a terminal device needs to be disconnected during network handover. A specific solution is as follows: The terminal device detects a network parameter of a first Wi-Fi network for connecting the terminal device to the access point device; the terminal device initiates scanning when the network parameter meets a preset condition; the terminal device obtains authentication information of a second Wi-Fi network if the terminal device obtains the second Wi-Fi network of the access point device through scanning and the terminal device is associated with the second Wi-Fi network, where service set identifiers SSIDs of the second Wi-Fi network and the first Wi-Fi network are different; the terminal device accesses the second Wi-Fi network; and the second Wi-Fi network reuses an established protocol stack link between the terminal device and the first Wi-Fi network for communication.
